Sheet piling in box form



J. MEISER gnam nuns IAN Box FORM July 15,; 1930.

Filed July 1o`, 1929 Patented .lilly l5, 193@ N'l" OFFCE JOSEF Marsan., or DORTMUND, GERMANY SHEET FILING IN BOX FORM Application led July 10, 1929, Serial No. 377,241, and in Germany May` 31, 1928.

such a way as to leave suliicient room tor theV plates constituting that. side to yield in the direction of the wall withoutendangering the stability of the latter.

It desired or it found necessary, channel members can be inserted in the wall, to provide balanced ramming and t-o allord spaces for accommodating structural members.

Typical embodiments ci' the invention are Y V2o illustrated by the accompanying drawing whereon Fig. l represents a cross section oi one form and F ig. 2 a similar view of a slightly modii'ied form. Y p

As shown, the wall consists of two rows ot' metal plates a and c7), with interposed lsection members c. rlhe plates a are connected together by closely litting joints Z inlrnown manner ,but the plates Z) on the opposite side of the box wall are each provided at one end with aprojection c behind which engages the offset end f of the adjoining plate. rlhe connection eaf'precludes lateral slipping while affording the possibility for slipft-o occur in the longitudinal direction of the wall 'so as to counteract the irregularities that are inevi table in the rolling of the various plates. Said connection may, of course, be of a dif,-

ferent design, the essential point being the' possibility of movement `in the .longitudinal direction of the wall.

The wall shown in Fig. 2 is the same as that shown in Fig. l, except that a channel member g is inserted to provide balanced ramming and forthe accommodation of structural members. In this case the wall can be closed towards the rear by an iron plate h,

but this is unnecessary in most instances.

I claim Vbetween said plates, and jointing means integral with the plates of the other row permitting relative movement in the longitudinal direction of the wall.

3. A sheet piling wall of box formation comprising spaced rows ot metal plates, I-sections interposed between said rows, jointing means integral with the plates of one row to provide close-tltting connections between said plates, and jointing means integral with the plates of the other row permitting relative movement in the longitudinal direction of the wall.

4. A sheet piling wall of box formation ycomprising spaced rows of metal plates, I-

sections interposed between said rows, a channel member inserted in one r-ow, .jointing means integral with the plates of one row to provide closetitting Vconnections between said plates, and jointing means integral with ther plates of the other row permitting relative movement in the longitudinal direction ot the wall.,

In testimony whereof l affix my signature.
